Discreet Recording with Software Control

Wallet-Size Design

The card format keeps the recorder inconspicuous during everyday use. It can record inside a wallet, although surrounding materials and placement affect sound pickup.

Scheduled Recording

Set recording times by day and date, or use voice activation for sessions with pauses between conversations.

Protected File Access

The USB card reader and dedicated software provide access to recordings and settings. Password protection restricts access; time stamps identify each session.

Full Description

A Recorder in a Credit Card Format

REC-CARD is designed for discreet, local audio recording. The standard card is 1.6 mm thick, with no visible buttons or connectors on its exterior. A two-finger swipe along the magnetic stripe turns it on or off. The concealed recording LED can be disabled.

The built-in lithium-polymer battery provides up to 35 hours of recording or up to 150 hours on standby under ideal conditions. Actual runtime varies with settings and use. The standard version has a 90 dB dynamic range and supports sampling rates of 8, 16, and 24 kHz.

Voice Activation and Recording Schedules

VAS voice activation lets the recorder respond to sound instead of recording every quiet interval. The software also provides start and stop timers and recording schedules for individual days and dates.

With loop recording enabled, new audio replaces the oldest files when memory is full. Save recordings you need to retain before they are overwritten. Scheduled sessions depend on available battery power and storage.

File Management and Access Protection

The USB card reader connects REC-CARD to a computer for use with the management software. Recordings carry date and time stamps. Password-protected access limits who can retrieve stored audio or change settings.

The system also supports a digital signature for audio-file authentication. File authentication and password protection serve different purposes.

Separate Remote-Control Version

The RF remote-control model has a 1.5 mm card, 2 GB of memory, and a four-channel remote with a range of up to 15 m (49 ft). It offers up to 52 hours of continuous recording under ideal conditions. Actual runtime and remote-control range depend on use and operating conditions.

Its memory holds up to 150 hours at 8 kHz using 4-bit ADPCM. With RF switched off and voice activation enabled, runtime can reach up to eight days under ideal conditions, depending on sound activity. These figures describe different operating modes.

PCM and ADPCM are different encoding options. The 4-bit figure refers to ADPCM encoding; it is not equivalent to 16- or 24-bit PCM resolution.

Custom Configurations

Optional GPS

GPS locator integration is available on request at additional cost, separately from the standard audio recorder.

Custom Card Graphics

Custom graphics are available at additional cost. The design and hardware configuration are discussed when ordering.

Contactless Payment Configuration

A custom build can incorporate the chip from an existing payment card for contactless use, alongside the recorder and optional location tracking. This requires an individually assessed configuration and is not a feature of the standard card.

Applications

Interviews and Meetings

The card format allows audio to be recorded without placing a conventional recorder on the table. Date and time stamps help identify sessions during review.

Scheduled Documentation

Start and stop timers support appointments or recurring sessions planned in advance. Voice activation is useful where conversations are separated by quiet periods.

Professional Field Recording

The slim format fits a wallet for portable recording. The optional RF remote provides control from nearby, while password-protected software access helps restrict access to stored files.

Frequently Asked Questions

Can REC-CARD record while it is in a wallet?

Yes. It is designed to work inside a wallet. Wallet material, placement, and surrounding noise affect sound pickup.

How do I turn it on without a visible button?

Slide two fingers along the magnetic stripe to switch the standard card on or off. Its concealed recording LED can be disabled.

What is the difference between the versions?

The standard version is 1.6 mm thick and offers up to 35 hours of recording. The RF remote-control version is 1.5 mm thick, has 2 GB of memory, and offers up to 52 hours of continuous recording. These runtime figures are under ideal conditions; actual runtime varies with use.

Does the RF remote let me listen live?

The RF feature provides remote control, with a range of up to 15 m (49 ft). It is not described as a live audio link. Stored recordings are accessed using the card reader and software.

Can I schedule recordings?

Yes. The software supports schedules by day, date, and time, with start and stop timers. Voice-activated and manual recording are also available.

What happens when memory fills up?

With loop recording enabled, new recordings overwrite the oldest files. Save important audio before it is replaced.

Do the 150 hours refer to battery life or storage?

For the standard version, 150 hours is maximum standby runtime under ideal conditions. For the remote-control version, 150 hours is storage capacity at 8 kHz with ADPCM. These are separate specifications.

Are GPS and contactless payment features included?

No. They are custom options. GPS integration is available at additional cost. A contactless payment configuration requires assessment of the existing card chip and requested build.
